Description
Technical field
The present invention relates to a kind of processing method of automobile-used parts, particularly relate to a kind of press-processing method of automobile crankshaft signal panel.
Background technology
Existing thin-walled plate-like class, covering elements, as automobile crankshaft signal panel, be made up of signal panels chassis and the signal panels side ring linked together, its face of trying to get to the heart of a matter is for there being pore structure (comprising center positioning hole and installing hole), side ring is distributed with large-signal hole and closely spaced square small-signal hole, because the high H of side ring and distance between borehole D is less, bring extreme difficulties to processing.Domestic and international at present also do not have desirable processing method to this thin-walled plate-like class, covering elements, traditional processing method can only be taked: get the raw materials ready, blanking, punching press, deflashing, punching, first will try to get to the heart of a matter and process, then with bored the side ring assembly welding in square signal hole, most rear car except unnecessary weldering trace.
The drawback existed is:
1. due to the irregular metal flow of material surface when being shaped, stress state is inconsistent everywhere, and distortion skewness causes signal panels yielding;
2. boring trouble, turnery processing location difficulty, element precision is low, easily produces the such as defect such as fold, crackle;
3. operation is many, very complicated, and stock utilization is low, and the production cycle is long, and efficiency is low, and cost is high, can not adapt to the requirement of producing in enormous quantities;
4., in order to overcome above defect, in production practices, need to rely on the experience of designer, by die trial repeatedly and repair a die, adjusting process parameter makes up, but even so, still cannot eliminate above defect at all.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of press-processing method of automobile crankshaft signal panel, to overcome the above-mentioned deficiency existing for prior art.
The technical scheme that the present invention takes is: a kind of press-processing method of automobile crankshaft signal panel, comprises the steps:
(1) blanking: by monoblock sheet metal stamping-out squarely blank;
(2) punching, indent: use the circular blanket that punching, indent compound die are once-forming, stock of square is struck out following process structure:
A. radius R=the R1+R0+H+H0 of described circular blanket, wherein R1 is the radius on signal panels chassis, and R0 is shaped form lead-over groove punching press surplus, and H is signal panels side ring height, and H0 is signal panels side ring trimming allowance;
B. signal panels chassis stamps out center positioning hole and installing hole;
C. chassis respective radius R1 circumferentially, namely the joint of chassis and signal panels side ring strike out a shaped form lead-over groove;
(3) punching press large-signal hole: use large side opening mould to stamp out large-signal hole on signal panels side ring;
(4) punching press small-signal hole: use spaced small side hole module, namely establish the small side hole module of a casement at interval of a hole, punching press at twice on signal panels side ring, first time stamps out 1/2 small-signal hole, then circular blanket is rotated the angle in a hole, complete the punching press in remaining 1/2 small-signal hole;
(5) drawing: use Drawing Die to carry out bending drawing, makes the side ring of circular blanket along shaped form lead-over groove flange 90 °, forms signal panels blank;
(6) repair thorn, shaping, trimming: use that engine lathe repaiies thorn to the signal panels blank processed through above-mentioned operation, shaping, trimming car remove unnecessary ring limit, side ring top, obtain signal panels finished product;
(7) machine.
Its further technical scheme is: the sheet metal of described making stock of square is S355MC hot rolling acid-cleaning steel plate, and its thickness S is 2.5mm.
Its further technical scheme be: described punching, indent compound die, large side opening mould, small side hole module and Drawing Die adopt alloy mold Steel material to make.
Owing to adopting technique scheme, the press-processing method of a kind of automobile crankshaft signal panel of the present invention has following beneficial effect:
1. use the press-processing method of a kind of automobile crankshaft signal panel of the present invention, complicated loose structure class disk body, covering elements-crankshaft signal dish can be made to make by adopting stamping technique, operation is few, time saving and energy saving, be conducive to realizing automation to produce in enormous quantities, enhance productivity, reduce production cost;
2. the press-processing method of a kind of automobile crankshaft signal panel of the present invention solve the three-dimensional blank of traditional circular thin-wall stamping time due to the irregular metal flow of material surface, stress state is inconsistent everywhere, problem such as distortion skewness etc., has that stock utilization is high, with short production cycle, plastic force is little, element precision advantages of higher;
3. during drawing band orifice, when the hole of edge on the distance L(and side ring of flexural center in hole base with try to get to the heart of a matter the ultimate range of inner surface) too small time (L is less than 1.5 ~ 2S, S is material thickness), drawing hole when is easily out of shape, the present invention takes to buckle the technique of linear lead-over groove on drawing transition limit, make the turning rounding off of bending drawing, preferably resolve the problem on deformation of drawing metapore, after solving complex structural member drawing simultaneously disk body easily ftracture, fold, the problem such as distortion;
4. because the telltale hole interval of signal panels disk body side ring is close, pitch-row is very little, it is material thickness that distance D between two small-signal holes is less than 2S(S), require high as once stamping to mould, the present invention adopts and goes out close hole for twice, thus solves the strength problem of mould preferably;
5. a kind of automobile crankshaft signal panel of the present invention press-processing method operation and control simple, environmental pollution is little, can be applicable to the production in enormous quantities of auto parts and components.
Be further described below in conjunction with the technical characteristic of drawings and Examples to the press-processing method of a kind of automobile crankshaft signal panel of the present invention.
